41 ohm termination

50 ohm termination – best matching

57 ohm termination

Bandwidth estimation (50 ohms) send in edge – pulser -> t-line -> scope rising time (10-90%) ~ 250 ps pulser -> scope rising time ~160 ps add rising time contributions in quadrature: t2total=t2instrument + t2line ------> tline = 190 ps 3 dB BW ~ 1.8 GHz
